Washington DC - A US official said Sunday that Washington and Tehran agreed to halt attacks after new strikes strained their interim deal, with the sides planning to renew talks aimed at ending the Middle East war.

The exchanges have underscored the fragility of a Pakistan-brokered agreement to end the conflict that has killed thousands and snarled the flow of oil shipments through the vital Strait of Hormuz.

Although a ceasefire took effect in April, sporadic violence has flared up in the Gulf region, with traffic in the strait serving as a regular flashpoint.

"Technical talks are slated to continue on all areas of the MOU," a US official told AFP in an email late Sunday, referring to the memorandum of understanding struck between Washington and Tehran.

"Both sides will stand down for now and vessels can move freely" in and around the Strait of Hormuz, the official added.

Iran has not immediately commented on the US statement, and the US official did not confirm a media report that talks would resume Tuesday in Qatar.

Tehran has insisted on controlling passage through the vital strait, through which about a fifth of the world's oil and liquefied natural gas travel in peacetime. It did not have that control before the war.

Iran's top diplomat warned Sunday that any attempt by ships to bypass its preferred route through Hormuz would "increase tensions" in the Middle East.

The strait comprises Omani and Iranian territorial waters, but under customary international law, the two cannot generally block passage or charge tolls.

Nevertheless, Iran prevented most ships from using the narrow waterway during the war, granting it enormous economic leverage.

Tehran's enforcement of its control has sparked repeated flare-ups with Washington, the latest of which came early Sunday, when US Central Command said it had attacked 10 Iranian military targets over "continued Iranian aggression against commercial shipping."

Iran said it retaliated with strikes against US bases in Kuwait and Bahrain. Both Kuwait and Bahrain denounced the Iranian attacks.

Iran presently insists ships transiting the strait pass through a corridor near its own shores, though this week dozens of vessels have traveled along the opposite side of the waterway, hugging the Omani coast.

"Any attempt to adopt new or separate arrangements compared to what is underway by the Islamic Republic of Iran, will only lead to more complicated situations and delays in the reopening of the Strait of Hormuz, and will increase the tensions," Iranian Foreign Minister Abbas Araghchi said.

The published text of the memorandum says Iran will define the future administration of the strait in dialogue with Oman and the other Gulf States, but "in line" with international law.

Iran's Revolutionary Guards said they were taking measures to control traffic in the strait and that vessels violating those measures would be dealt with more firmly than before.

Mohammad Mokhber, adviser to Iran's supreme leader, wrote on X that as long as Iran managed the strait, Washington's "hegemonic dreams in the region will not be realized."

Experts said there would likely be more Hormuz incidents.

While the tit-for-tat exchanges have largely been without reported casualties, Qatar's interior ministry said one of its citizens was killed aboard a boat by shrapnel from "military operations in the area."
